Sources & methodology

We prioritize official sources over secondary ones, roughly in this order: national legislation or the relevant government authority; official road, toll, police, or transport authorities; supranational sources such as the EU or UNECE; official embassy or consular guidance; and official rental or insurance terms for company-specific requirements. Established motoring associations are used as supporting sources, not as the sole basis for a legal claim.

Each country page links to the primary official source we used, under “Official sources.” Where a rule is genuinely conditional or varies by circumstance, we say so rather than stating a single absolute answer.

Not every rule carries the same risk if it goes stale, so review frequency is risk-based. Claims that affect whether you can legally drive at all — licence acceptance, International Driving Permit requirements, insurance, and border documents — get reviewed most often. Tolls, vignettes, low-emission zones, and winter-equipment rules are next. Speed limits, alcohol limits, and mandatory equipment change less often and are reviewed on a longer cycle.

The date shown on every country page is when we last checked that page against its sources — it’s a review date, not a guarantee that nothing has changed since. Rules can change with little notice, especially fines, tolls, and seasonal requirements, so always confirm anything time-sensitive against the official source linked on the page before you rely on it.

If you spot outdated information, a broken official link, conflicting official guidance, a missing exception, or a tool result that looks wrong, we’d rather hear about it than have it sit uncorrected. Email support.road.clarity@gmail.com with the page URL and what looks wrong — a link to an official source is helpful but not required. Corrections are reviewed before anything is changed; we don’t auto-publish edits.

Road Clarity is a reference tool for trip preparation, not legal advice — see our Terms for the full disclaimer. When a rule genuinely depends on your specific situation, confirm it with an official source or the relevant authority before you travel.
